Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world. About 1C of total warming. Second chart: about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability. Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases. About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

Wow. There is even a Wikipedia page on droughts in California.
This is frightening stuff for someone accustomed to a much more even weather.

Yeah its a pretty big issue with socal especially. The state and federal governments are going to have to eventually deal with California and other nearby states importing an unsustainable amount of water from nearby water sources.

Yeah, growing alfalfa in the desert for export as cattle fodder is just bonkers, but we do it because the farmers there have senior rights to Colorado River water

Arizona has Saudi owned corporations sucking the aquifer for alfalfa export. Oof
